Hi, I have a character vector as below:
a<-c('10','3R','4','4R','5','5R','6','6R','7','8','9','7R','1','10R','11'
,'11R','12','12R','13','13R','14','14R','15','15R','1R','2','2R','3','8R'
,'9R')
Is there a clever way to sort this easily to return a vector of index that
would
produce a vector as below:
a[index]:
[1] "1" "2" "3" "4" "5" "6" "7" "8" "9" "10"
[11] "11" "12" "13" "14" "15" "1R" "2R" "3R" "4R" "5R"
[21] "6R" "7R" "8R" "9R" "10R" "11R" "12R" "13R" "14R" "15R"
Thanks,
John
